Revolutionary soldier -- no communist -- brushed aside (7)
I believe the answer is:
ignored
'brushed aside' is the definition.
('ignore' can be a synonym of 'brush aside')
'revolutionary soldier no communist' is the wordplay.
'revolutionary' says the letters should be written backwards (letters revolve around).
'soldier' becomes 'GI' (term for US soldier).
'communist' becomes 'red' (red can informally mean communist).
'gi' back-to-front is 'ig'.
'ig'+'no'+'red'='IGNORED'
(Other definitions for ignored that I've seen before include "cast aside" , "Paid no attention to" , "Neglected" , "Passed over" , "Paid no heed" .)
